Primary Outcome Measures:

The primary objective is to assess the bioequivalence of one risedronate 150 mg tablet versus two risedronate 75 mg tablets administered as a single oral dose. [ Time Frame: 18-21 days ] [ Designated as safety issue: No ]

Enrollment:	96
Study Start Date:	January 2008
Study Completion Date:	April 2008
Primary Completion Date:	February 2008 (Final data collection date for primary outcome measure)

Arms	Assigned Interventions
1: Experimental One risedronate 150 mg tablet administered orally after an overnight (10 hour) fast, followed by a 4 hour post-dose fast	Drug: Risedronate 1 risedronate 150 mg tablet administered orally
2: Active Comparator Two risedronate 75 mg tablets administered as a single oral dose after an overnight (10 hour) fast, followed by a 4 hour post-dose fast	Drug: Risedronate 2 risedronate 75 mg tablets administered as a single oral dose

Detailed Description:

The data to support the interchangeability of one risedronate 150 mg tablet versus two risedronate 75 mg tablets as monthly dose forms is primarily based on the similarity of in vitro dissolution and an in vivo study, which showed risedronate absorption is not dissolution rate limited. These results suggest that monthly dosing of risedronate may be accomplished by administration of either one risedronate 150 mg tablet or two risedronate 75 mg tablets. The purpose of this study is to provide additional clinical data to support the interchangeability of these 2 dose regimens.
